If you want to provide a stack trace you got on an HTML page, be sure to
provide the plain text version, which should appear at the bottom of the
page. Do not provide it as a screenshot, since search engines will not be
able to index the text inside them. Same goes for errors encountered in a
terminal, do not take a screenshot, but copy/paste the contents. If
the stack trace is long, consider enclosing it in a <details> HTML tag.
Be wary that stack traces may contain sensitive information, and if it is
the case, be sure to redact them prior to posting your stack trace.
